proposal: rename DLT_PRISM_HEADER

I propose to change the DLT_PRISM_HEADER semantics. I am trying to identify the stakeholders in such a change, to find out what they think. I figure some of them read this list. For DLT_PRISM_HEADER, libpcap expects a header that is a whopping 144 bytes long. It does not resemble any header a Prism radio will give, so the name DLT_PRISM_HEADER for it is misleading. Examining linux-wlan-ng and ethereal, the header actually consists of length-type-value (LTV) tuples for received signal strength, PHY type, and other radio parameters. This seems like a stab at a generic 802.11 radio header. Why, then, is it not called DLT_IEEE802_11_RADIO, for example? The former name is misleading. I ask because I am adding to NetBSD a DLT whose header contains the portions of the Prism header preceding the IEEE802.11 header. I have tentatively called it DLT_SHORT_PRISM_HEADER, to avoid clashing with DLT_PRISM_HEADER, but I prefer to rename the old DLT_PRISM_HEADER to DLT_IEEE802_11_RADIO, and to call the Prism-specific header DLT_PRISM_HEADER.
